makecab & expand command lines

I want to make a wise script which expand cab-files to my computer. I made the cab-files with the command line makecab.exe /f "mycab.ddf". Now I have the folders "disk 1" until "disk 10" with the included cab-files and under the root folder a setup.inf + setup.rpt file. How can I automatically expand this file now with a wise script to my machine?

Thanks, but I think I made something wrong in the ddf-file header. If I try to expand the cab-file I get a error message " Install.cab is not Disk 2 File Name 2". Expand command couldn't find the "Disk 2" folder to continue with extracting of the files.

Ok, I'll found the failure in the DDF-file. I have to comment out the ".Set CabinetNameTemplate=Install.cab" line and then makecab.exe generate 1.cab, 2.cab and so on but the expand command still end up with an error. If I extract the CAB-files with WinZip all works fine.

1. I have a legacy setup with source files over 6,5 GB and I want to compress them.
2. I made a script wich creates the DDF-file and executes makecab.exe. As result I get the 1-11.cab in different folder named Disk 1 until Disk 11 + a setup.inf file in the root folder.(That works now)
3. I want to expand them with a script to a local folder and afterwards I want to run the setup.

My question is: Why do I get still a error message with the expand command?
